The way in which light interacts with objects in a scene can dramatically affect the final result.

Proper lighting can create the illusion of depth and dimension in a 3D scene. Shadows, highlights, and other lighting effects can make objects appear more three-dimensional, giving them a greater sense of realism.

Lighting can be used to create a specific mood or atmosphere within a scene. Bright, warm lighting can create a cozy, inviting feeling, while cool, dim lighting can create a more mysterious or ominous atmosphere.

Lighting can also enhance the texture and detail of objects in a scene. By casting shadows and highlights across a surface, lighting can create the illusion of bumps, ridges, and other details that might not otherwise be visible.

Lighting can help to establish the context of a scene, by suggesting the time of day, location, and other important factors. For example, a scene lit with warm, golden light might suggest a sunset or sunrise, while cool blue lighting might suggest a night scene.

Overall, lighting plays a critical role in creating a believable and immersive 3D scene. Even the most detailed models and textures will fall short without proper lighting to bring them to life.
